Maps are for everyone: Firstly, its interesting to note the difference between Geo in the USA and in the UK - here, geography is a core school subject so if you put on a GTI you'd mostly attract geography teachers. STEM teachers would mostly stay away - I predict they'd say 'maps are for geographers'. In the States, geography is far less strong at school level so a range of teachers from many subjects showed up to learn what Google Geo tools could do for them. Geo tools are now so easy to use that they can be used across subjects and it would be good if this could done in the UK too.
